Description

Technical Field

[0001] This invention relates to the field of moxibustion therapy equipment technology, and in particular to a moxibustion device. Background Technology

[0002] In the field of modern medicine and healthcare, moxibustion, as a traditional Chinese medicine therapy, is widely used in the treatment and conditioning of various chronic diseases and sub-health conditions due to its unique effects of warming and unblocking the meridians, dispelling cold and dampness, and regulating qi and blood.

[0003] Traditional moxibustion devices are mostly limited by the fixed layout of the moxa head, making it difficult to adjust to different patients' body shapes, thus affecting the effectiveness. Furthermore, there is a lack of dedicated positioning tools when placing the moxa stick in the combustion device. If it is placed directly in a container, the contact between the burning surface and the surface can affect the combustion effect. Sometimes, the device needs to be moved back and forth around the treatment area, and the moxa stick moving around inside the container can easily burn it. Moreover, the distance between the burning surface of the moxa stick and the recipient's skin needs to be carefully controlled; too close, and there is a risk of burns; too far, and the heat is insufficient, affecting the moxibustion effect and the user experience. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the present invention provides a moxibustion device.

[0005] The technical solution of this invention is as follows:

When the cover is placed on the first pressure plate, the locking post and the locking block enter the circular hole of the first locking groove. When the cover is rotated, the locking post enters the arc-shaped waist-shaped hole of the first locking groove. The locking block is located below the bottom end of the first pressure plate, and the top surface of the locking block abuts against the bottom surface of the first pressure plate, so that the cover is locked inside the first pressure plate.

[0011] Preferably, the locking assembly further includes: a second pressure plate, a locking block, and a double-ended stud. The second pressure plate is disposed on the side wall at the top of the combustion chamber, and the first pressure plate is disposed above the second pressure plate.

A movable groove is formed on the second pressure plate, and the locking block is disposed in the movable groove. The width of the movable groove is greater than the width of the locking block. A second slot is formed on the locking block. The locking block passes through the first slot and enters the second slot. When the cover rotates, the locking block pushes the locking block to move closer to the center of the combustion chamber, so that the locking block partially extends out of the movable groove to lock the second pressure plate.

[0027] The present invention will now be further described with reference to the accompanying drawings and embodiments:

[0028] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, a moxibustion device is provided, which includes: an outer shell 10, a first control module 20 and a cover 40. The outer shell 10 has a combustion chamber 101, which provides space for the moxa stick to burn. The bottom of the combustion chamber 101 has a heat application port 102, from which the hot air from the burning moxa stick comes out. The control module is disposed in the mounting cavity 108. The cover 40 is disposed on the top of the outer shell 10 and seals the combustion cavity 101. The bottom of the cover 40 is provided with a mounting box 30. The horizontal cross-section of the mounting box 30 is circular. The mounting box 30 has an internal receiving cavity 301. The receiving cavity 301 is provided with a temperature control module 21, a first control module 20, a deflection voltage module 22, a heat dissipation module 23, and a power supply module 24. The power supply module 24 is electrically connected to the first control module 20 to supply power to the first control module 20. The first control module 20 is electrically connected to the deflection voltage module 22 and the temperature control module 21. The deflection voltage module 22 is electrically connected to the heat dissipation module 23. The temperature control module 21 has a cooling side and a heating side. The first side of the temperature control module 21 faces the side wall of the bottom of the receiving cavity 301 in the mounting box 30. The heat dissipation module 23 is connected to the bottom surface of the housing. The top of the cover 40 has a heat dissipation hole communicating with the receiving cavity 301, allowing the heat dissipation module 23 to expel heat from the receiving cavity 301. The bottom of the mounting box 30 has a through hole 302 communicating with the receiving cavity 301. A guide plate is provided on the temperature control module 21, extending through the through hole 302. A memory alloy spring 50 is provided on the guide plate, with the other end of the spring connected to the placement member 54, on which the moxa stick is placed. A detection module 25 is provided on the bottom surface of the mounting box 30, and the detection module 25 is electrically connected to the first control module 20. After the moxa stick on the placement piece 54 is lit, the detection module 25 detects the spatial position of the moxa stick within the combustion chamber 101, i.e., the distance between the ignition point of the moxa stick and the detection module 25. The detection module 25 sends the real-time distance of the ignition point of the moxa stick to the first control module 20. The first control module 20 controls the application of a forward or reverse current to the temperature control module 21 based on the distance information, causing the first side of the temperature control module 21 to cool or heat. The conduction element 51 heats or cools the shape memory alloy spring 50, allowing the shape memory alloy spring 50 to move the moxa stick on the placement piece 54 up and down, thus ensuring that the ignition point of the moxa stick is always in the optimal position, achieving the best moxibustion effect. It should be noted that when the first control module 20 applies a forward current and a reverse current to the temperature control module 21, it simultaneously supplies power to the heat dissipation module 23, enabling the heat dissipation module 23 to dissipate heat from the receiving cavity 301 in conjunction with the heat dissipation holes. It should also be noted that the shape memory alloy spring is made of nickel-titanium alloy.

[0029] Specifically, such as Figure 7 and Figure 8As shown, the first control module 20 controls the deflection voltage module 22 according to its internal preset program, so that the deflection voltage module 22 applies a reverse voltage to the temperature control module 21, which heats the first surface of the temperature control module made of material 21. The heat is transferred to the shape memory alloy spring 50 through the conductive member 51. The shape memory alloy spring 50 stretches when heated, causing the moxa stick on the placement member 54 to move downward. When the shape memory alloy spring 50 needs to return to its initial position, the first control module 20 controls the deflection voltage module 22 to apply a positive voltage to the temperature control module 21, which cools the first surface of the temperature control module 21. The conductive member 51 cools the shape memory alloy spring 50, causing the shape memory alloy spring 50 to contract to its initial length.

[0030] Among them, the first control module 20 is model ESP32, the detection module 25 is model VL53L0X, the deflection voltage module 22 is an H-bridge, the temperature control module 21 is model TEC1-12703, and the power supply module 24 is 12V DC.

[0031] The output pin of the power supply module 24 is electrically connected to the input pin of the first control module 20, and the GND pin of the power supply module 24 is electrically connected to the GND pin of the first control module 20.

[0032] The VCC pin of the detection module 25 is electrically connected to the input pin of the first control module 20, the GND pin of the detection module 25 is connected to the GND pin of the first control module 20, and the SDA and SCL pins of the detection module 25 are electrically connected to the I²C and SCL pins of the control module.

[0033] The PWM output pin of the first control module 20 is electrically connected to the PWM input pin of the H bridge, the enable control pin of the first control module 20 is electrically connected to the enable pin of the H bridge, the GND pin of the first control module 20 is electrically connected to the GND pin of the H bridge, and the output power supply pin of the first control module 20 is electrically connected to the power input pin of the H bridge.

[0034] The first output pin of the H-bridge is electrically connected to the positive pin of the temperature control module 21, the second output pin of the H-bridge is electrically connected to the negative pin of the temperature control module 21, the power input pin of the H-bridge is electrically connected to the output pin of the power supply module 24, and the GND pin of the H-bridge is electrically connected to the GND pin of the power supply module 24.

[0035] After the above configuration, the first control module 20 is powered on and initializes the H-bridge, temperature control module 21, and detection module 25. After the moxa stick is lit, the detection module 25 detects the ignition point position of the moxa stick in real time and calculates the real-time distance of the ignition point. The detection module 25 sends the real-time distance to the first control module 20. The first control module 20 analyzes the real-time distance of the moxa stick according to the preset program. For example, if the distance of the moxa stick is less than the distance threshold preset by the program, the PWM output pin of the first control module 20 sends a high level to the PWM input pin of the H-bridge. The enable control pin of the first control module 20 and the enable pin of the H-bridge send a high level. At this time, the first output pin of the H-bridge outputs a low potential, and the second output pin of the H-bridge outputs a high potential, so that the H-bridge can apply a reverse voltage to the temperature control module 21, thereby causing the first surface of the temperature control module 21 to heat up. The conductive element 51 conducts the heat to the memory alloy spring 50. The memory alloy spring 50 stretches when heated, causing the moxa stick to move downward. When the shape memory alloy spring needs to contract, the PWM output pin of the first control module 20 sends a low level to the PWM input pin of the H-bridge, while the enable control pin of the first control module 20 and the enable pin of the H-bridge send a high level. At this time, the first output pin of the H-bridge outputs a high potential, and the second output pin of the H-bridge outputs a low potential, thereby enabling the H-bridge to apply a positive voltage to the temperature control module 21, causing the first side of the temperature control module 21 to cool down. This cools the shape memory alloy spring 50 through the conductive element 51, causing the shape memory alloy spring 50 to contract. It should be noted that the elongation and contraction of the shape memory alloy spring 50 are controlled by the timing of the level sent by the first control module 20 to the PWM input pin and the enable pin of the H-bridge, thus preventing the shape memory alloy spring from over-elongating or over-contracting.

[0036] Specifically, such as Figure 7 As shown, a temperature measuring module 201 is also installed in the mounting cavity 108. The temperature measuring module 201 is a DS18B20 model. Its VCC pin is electrically connected to the input pin of the first control module 20, its GND pin is electrically connected to the GND pin of the first control module 20, and its DATA pin is electrically connected to the communication pin of the first control module 20. The temperature measuring module 201 is used to detect the real-time temperature of the memory alloy spring 50. Based on the temperature of the memory alloy spring 50, the temperature measuring module 201 is electrically connected to the first control module 20. The first control module 20 can calculate the time for sending levels to the H-bridge PWM input pin and the H-bridge enable pin according to a preset program, thereby achieving real-time control of the elongation and control quantity of the memory alloy spring 50, ensuring that the ignition point of the moxa stick is always at the optimal position.

[0037] Specifically, the bottom of the cover 40 is provided with external threads, and the side wall of the receiving cavity 301 of the mounting box 30 is provided with internal threads. The internal threads are threadedly connected to the external threads, realizing a detachable connection between the mounting box 30 and the cover 40. The cover 40 is made of polyimide, which is resistant to high temperatures.

[0038] Specifically, such as Figure 7 and Figure 8 As shown, a transparent heat insulation cover is provided at the bottom of the mounting box 30. The detection module 25 is located inside the heat insulation cover. The heat insulation cover can isolate the heat inside the combustion chamber 101, preventing the detection module 25 from being damaged by heat. Moreover, the transparent heat insulation cover will not affect the detection module 25's detection of the burning distance of the moxa stick.

[0039] In this embodiment, as Figures 5 to 7 As shown, a heat insulation tube 52 is provided on the back of the mounting box 30. The heat insulation tube 52 is hollow and is used to delay the loss of surface temperature of the shape memory alloy spring 50. A limiting ring 53 is provided inside the heat insulation tube 52. The two ends of the limiting ring 53 are fixedly connected to the side wall of the heat insulation tube 52. The shape memory alloy spring 50 is located inside the limiting ring 53. The limiting ring 53 can restrict the movement direction of the shape memory alloy spring 50, thereby guiding the shape memory alloy spring 50 to contract and stretch in the correct direction.

[0040] Specifically, a groove is formed on the side wall of the heat insulation tube 52, and a slider is provided on the outer surface of the placement member 54, which is slidably disposed within the groove. When the shape memory alloy spring 50 extends, the slider and the groove work together to smoothly drive the moxa stick up and down. To prevent the placement member 54 from slipping off the heat insulation tube 52, a stop is provided at the end of the groove to close it. A pin 55 is provided on the placement member 54, and the moxa stick to be lit is inserted into the pin 55.

[0041] In this embodiment, as Figures 5 to 7A receiving tray 56 is provided on the end face of the placement component 54. A smoke outlet 58 is formed between the top surface of the receiving tray and the bottom surface of the heat insulation tube 52. The vertical distance of the smoke outlet 702 is greater than the length of the moxa stick. This design ensures that the receiving tray 56 will not interfere with the raising and lowering of the moxa stick. An oil storage chamber 561 is provided inside the receiving tray 56, and a filter screen 57 with filter holes is provided inside the receiving tray 56. The filter screen 57 covers the oil storage chamber 561. When the moxa stick burns, the ash produced falls onto the filter screen 57, and the moxa oil produced drips through the filter holes into the oil storage chamber 561, preventing ash and oil from escaping from the heat application port 102 and improving ease of installation. In order to facilitate the installation and removal of the ash receiving tray 56, multiple connection holes are made around the surface of the ash receiving tray 56. The bottom surface of the heat insulation tube 52 is provided with threaded holes in the same number and position as the connection holes. The number of screws 73 equal to the number of connection holes passes through each connection hole in sequence and connects with each threaded hole, thereby realizing easy installation and removal of the ash receiving tray 56.

[0042] Specifically, mounting slots are spaced apart on the side walls of the ash receiving tray 56, and inserts are provided on the surface of the filter screen 57. The inserts are slidably disposed in the mounting slots, which facilitates the installation and removal of the filter screen 57. Two flow-blocking plates 59 are also spaced apart on the side walls of the oil storage cavity 561. The flow-blocking plates 59 are inclined from the sides of the oil storage cavity 561 toward the middle of the oil storage cavity 561. This arrangement can restrict the flow of moxa oil in the oil storage cavity 561 and prevent the moxa oil in the oil storage cavity 561 from falling out of the ash receiving tray 56 when the moxibustion device is moved.

[0043] In this embodiment, as Figures 2 to 4As shown, after the cover 40 is placed on the combustion chamber 101, the cover 40 is prone to loosening, which affects the heat application process. To solve the above technical problem, a moxibustion device further includes a locking assembly, which includes a first pressure plate 60, a second pressure plate 61, a locking block 62, and a double-ended stud 63. A stepped groove is formed on the side wall of the top of the combustion chamber 101. The second pressure plate 61 is locked in the stepped groove. The first pressure plate 60 is positioned above the second pressure plate 61. The second pressure plate 61 and the first pressure plate 60 are connected by the double-ended stud 63, so that the first pressure plate 60 and the second pressure plate 61 are fixed inside the outer shell 10 and the cover 40 is rotatably connected to the first pressure plate 60. A first slot 601 is formed on the first pressure plate 60, which consists of a circular hole and an arc-shaped waist-shaped hole. The second pressure plate 61 has a moving groove 611, and the locking block 62 is disposed within the moving groove 611. The width of the moving groove 611 is greater than the width of the locking block 62. The locking block 62 has a second slot 621. The horizontal cross-section of the moving groove 611 is an arc-shaped waist-shaped hole. The first slot 601 and the second slot 621 are interconnected. The cover 40 has a locking post 402, and a locking block 403 is disposed on the locking post 402. Both the locking post 402 and the locking block 403 are cylindrical. The area of ​​the locking block 403 is greater than the area of ​​the locking post 402. The area of ​​the circular hole in the first slot 601 is slightly larger than the area of ​​the locking block 403. The area of ​​the arc-shaped waist-shaped hole in the first slot 601 is greater than the area of ​​the locking post 402 but smaller than the area of ​​the locking block 403. The area of ​​the arc-shaped waist-shaped hole in the second slot 621 is greater than the area of ​​the locking block 403. When the cover 40 is placed on the first pressure plate 60, the locking pin 402 and the locking block 403 pass through the circular hole of the first locking groove 601, the locking block 403 enters the second locking groove 621, and the locking pin 402 is located in the first locking groove 601. Then, rotating the cover 40 causes the locking pin 402 and locking block 403 to rotate. The locking pin 402 and locking block 403 move from the circular hole of the first locking groove 601 to the arc-shaped waist hole of the first locking groove 601. At this time, the top surface of the locking block 403 abuts against the bottom surface of the first pressure plate 60. Since the area of ​​the locking block 403 is larger than the area of ​​the arc-shaped waist hole of the first locking groove 601, the locking block 403 is locked under the first pressure plate 60. When the locking block 403 moves synchronously in the second locking groove 621, it presses the side wall at the end of the second locking groove 621, causing the locking block 62 to move towards the combustion chamber 101. The locking block 62 extends out of the push groove, so that the locking block 62 locks the pin 402 and the second locking block 403. In this way, the cover 40 can be locked between the first pressure plate 60 and the second pressure plate 61 to prevent the cover 40 from shaking. Rotate the cover 40 in the opposite direction, and the locking pin 402 and the locking block 403 return to the circular hole of the first locking groove 601. The locking block 62, which is partially protruding from the push groove, also retracts into the push groove. Lifting it upwards will remove the cover 40 from the first pressure plate 60 and the second pressure plate 61.To enhance the locking effect of the cover 40, two locking posts 402 and locking blocks 403 are spaced apart at the bottom of the cover 40. Correspondingly, two first locking grooves 601 and two second locking grooves 621 are also provided on the first pressure plate 60 and the second pressure plate 61, respectively. The locking posts 402 and locking blocks 403, both with cylindrical horizontal cross-sections, reduce the movement resistance of the locking posts 402 and locking blocks 403 during movement, allowing the cover 40 to be smoothly locked between the first locking blocks 403 and the second locking blocks 403.

[0044] Specifically, two rotating blocks are spaced apart on the bottom end of the cover 40, and two rotating grooves are opened on the top surface of the first pressure plate 60. The rotating blocks are set in the rotating grooves. The rotating grooves are arc-shaped, and the horizontal cross-sectional shape of the rotating blocks is also arc-shaped. This arrangement can guide the rotation direction of the cover 40 within the first pressure plate 60 and reduce the rotational resistance of the cover 40 within the first pressure plate 60.

[0045] In this embodiment, as Figure 5 and Figure 6 As shown, the moxibustion device further includes a fixing component, which includes a screw 73 and a nut 74. A combustion furnace 70 is provided inside the combustion chamber 101. The top and bottom ends of the combustion furnace 70 abut against the second pressure plate 61 and the side wall of the bottom of the combustion chamber 101, respectively. An embedding groove is provided on the bottom side wall of the second pressure plate 61. An embedding block is provided on the top end of the combustion furnace 70. The embedding block is placed in the embedding groove. A plurality of first fixing holes are provided on the embedding block at intervals. Second fixing holes are provided at corresponding positions on the second pressure plate 61. One end of a plurality of screws 73 passes through each of the first fixing holes and each of the second fixing holes, and the other end is screwed to the other end of each screw 73 with a nut 74, thereby fixing the combustion furnace 70 inside the combustion chamber 101. The mounting box 30, the memory alloy spring 50, the heat insulation tube 52, and the placement component 54 are all located inside the combustion furnace 70. The combustion furnace 70 can retain the heat from the burning of the moxa stick, thereby improving the effect of moxibustion.

[0046] Specifically, such as Figure 5 and Figure 6 As shown, a heat-spreading mesh 71 and a fixing mesh 72 are spaced apart at the bottom of the combustion furnace 70, and are sequentially fitted onto each screw 73. The fixing mesh 72 is closer to the bottom of the combustion furnace 70. The heat-spreading mesh 71 has multiple heat-spreading holes 711, which are used to disperse the heat inside the combustion furnace 70, ensuring that the heat from the bottom outlet of the combustion furnace 70 is evenly applied to the user. The fixing mesh 72 provides fixed support; that is, a nut 74 is screwed onto the bottom of the fixing mesh 72 from the screw 73.

[0047] In this embodiment, as Figure 9As shown, a temperature sensor 26, an attitude detection sensor 27, and an infrared positioning sensor 28 are installed at the bottom of the outer casing 10. An installation cavity 108 is also provided inside the outer casing 10, and a second control module 29 is installed within the installation cavity 108. The temperature sensor 26, attitude detection sensor 27, and infrared positioning sensor 28 are all electrically connected to the second control module 29. Specifically, the temperature sensor 26 detects the temperature at the outlet of the heat exchanger 71, i.e., the hot compress port 102; the attitude detection sensor 27 detects the patient's posture; and the infrared positioning sensor 28 detects the distance between the outlet of the heat exchanger 71 and the user. The second control module 29 analyzes the data measured by the temperature sensor 26, attitude detection sensor 27, and infrared positioning sensor 28 and executes corresponding actions according to a preset program within the second control module 29, thereby providing the user with the best moxibustion experience. It should be noted that this moxibustion device can be used with an external moxibustion robot, which controls the movement of the moxibustion device. Specifically, the outer casing 10 has an assembly hole 105, through which a mechanical connection with the moxibustion robot can be achieved. This enables the moxibustion robot to control the movement of the moxibustion device according to the instructions issued by the first control module 20 and the second control module 29. It should be noted that the electrical connection between the temperature sensor 26, the attitude detection sensor 27, and the infrared positioning sensor 28 and the second control module 29 is the same as the connection principle of the first control module mentioned above, so it will not be described in detail.

[0048] In this embodiment, as Figure 5 and Figure 6 As shown, the moxibustion device also includes a heat insulation cylinder 80, which can be fixedly connected to the top side wall of the combustion chamber 101 using the aforementioned double-ended studs 63. The bottom end of the heat insulation cylinder 80 abuts against the bottom side wall of the combustion chamber 101. The combustion furnace 70 is located inside the heat insulation cylinder 80. The heat insulation cylinder 80 is used to insulate the heat emitted by the combustion furnace 70, preventing heat from entering the mounting cavity 108 and damaging the control module. Specifically, a heat insulation gap 801 is formed between the heat insulation cylinder 80 and the combustion furnace 70 to prevent the heat insulation cylinder 80 from being too close to the combustion furnace 70 and losing its heat insulation effect. A heat insulation sealing ring 81 is provided inside the heat insulation gap 801. The heat insulation sealing ring 81 is located above the temperature sensor 26, the attitude detection sensor 27, and the infrared positioning sensor 28. The heat insulation sealing ring 81 can insulate the heat between them, preventing heat from damaging the temperature sensor 26, the attitude detection sensor 27, and the infrared positioning sensor 28. It should be noted that both the heat insulation cylinder 80 and the heat insulation sealing ring 81 are made of iron-nickel based alloy.

[0049] In this embodiment, as Figure 5 and Figure 6As shown, the combustion furnace 70 is equipped with a smoke outlet pipe 701, and the outer casing 10 is equipped with a smoke extraction channel 104. The smoke outlet pipe 701 is connected to the smoke extraction channel 104, and the outer casing 10 is equipped with a chimney 103 connected to the smoke extraction channel 104. Multiple smoke outlets 702 are spaced apart on the side wall surrounding the combustion furnace 70, and the smoke outlets 702 are connected to the heat insulation gap 801. There is a gap between the bottom of the smoke outlet pipe 701 and the side wall of the smoke extraction channel 104, allowing the smoke extraction channel 104 to connect with the heat insulation gap 801. When the moxa stick is lit, the burning moxa stick produces smoke. It should be noted that this moxibustion device needs to be used in conjunction with an external negative pressure suction device. Connecting the negative pressure suction device to the chimney 103 allows the moxa smoke from the upper and middle parts of the combustion furnace 70 to be drawn out along the smoke outlet 701 to the smoke extraction channel 104. Moxa smoke deposited at the bottom of the combustion furnace 70 enters the heat insulation gap 801 through the smoke outlet 702 and can also be drawn out through the smoke extraction channel 104. This design prevents the accumulation of moxa smoke and avoids affecting the user's moxibustion experience.
